n. Ludwig Wittgenstein (1889-1951), Austrian philosopher who studied and taught at Cambridge University, author of "Philosophical Investigations"

(b. 1889, Vienna, Austria, d. 1951, Cambridge, UK). Wittgenstein’s most important contribution to psychology is his articulation of skepticism about traditional philosophical theories of what it is to possess a concept, or understand a word, which explain these capacities in terms of explicit knowledge of necessary and sufficient conditions.
